Compare Point vs Multipoint vs Broadcast

We have several type of communications to determined the method of connecting the host on network. There are point-to-point, multipoint and broadcast. This topic will be discriminate multipoint and point to point and broadcast

 

Table comparing:

Property	Point to point	Multipoint	Broadcast
Connection	One to one	One to multi stations	One to All stations
End stations	One	More	More and undefined
Security	Yes	Few	No
Spending	Few	More	more

Point to Point:

This is used in serial(một vài) communication. These type of communications transmitted solely( only one) the station at the opposite end device. No addresses are necessary. Only device connect to only device.

So, it’s the infinite security. Because don’t have another devices connecting in the same time, data only come in one device.

However, it’s very waste money. Simply meaning , we have to spend transmission equipment more than.

 

Some examples used it:

• EIA/TIA 232
• EIA/TIA 449
• X.25
• Frame Relay
• T-carrier
• OC3 – OC192

 

Multipoint

This is type of connect from one station to several other stations . Datas have been given to other stations that need to send. But don’t have broadcast, just only specific selected stations hear the replicated communication.

It’s the few security. Because, data have to send to many stations and maybe lost in transmission or stealing.

Some examples used it:

• Frame Relay
• ATM

 

Broadcast

 

Both communication and protocol. It will be send data to all stations have to connecting with it. This always using for information need to send to the stations without knowledge about it.

It doesn’t security. Because, data will dispersal in the network and don’t managed.

Some examples used it:

 

• Token Ring
• FDDI
• Ethernet
